This is cool!

Results of some testing:

 - a file in a read-only directory (for example Zooko's blog directory,
<URI:DIR2-RO:j74uhg25nwdpjpacl6rkat2yhm:kav7ijeft5h7r7rxdp5bgtlt3viv32yabqajkrdykozia5544jqa>),
   has Rename and Unlink entries in its context menu. These fail (as you
   would expect), but silently.

 - the Properties entry in the context menu produces only a small popup
   with just a close box.

 - choosing the View entry for a file gives an URL of the form
   '.../uri/URI:CHK:...'.
   Since this doesn't include the filename, the webapi server doesn't have
   sufficient information to infer the Content-Type from the name's
   extension. So for example, Zooko's wiki.html page is displayed as its
   HTML source:

<http://testgrid.allmydata.org:3567/uri/URI:CHK:2n3dpzhaqrdinlpyffvbini24a:u3kqzvyj7f7ldcbc5ahflpcqy66tv3hcu3t2hwv3wdhpp5ovvizq:3:10:864964>
   (URL modified to use the public testgrid gateway).

   What the WUI does in this case is to use an URL of the form
   '.../file/URI:CHK:.../@@named=wiki.html'
   which causes the webapi server to add a 'Content-Type: text/html' header.
   For example:

<http://testgrid.allmydata.org:3567/file/URI:CHK:2n3dpzhaqrdinlpyffvbini24a:u3kqzvyj7f7ldcbc5ahflpcqy66tv3hcu3t2hwv3wdhpp5ovvizq:3:10:864964/@@named=wiki.html>
